Scotland coach Scott Johnson believes South Africa can be contained if his team dominate the breakdown in Sunday's clash at Murrayfield.
The Springboks claimed a 30-17 victory over Scotland in Nelspruit in June but they had to dig deep to secure the win after trailing 17-6 early in the second half.
French referee Romain Poite was in charge of that match which saw Scotland winning the breakdown battle.
Poite's countryman Jerome Garces will referee Sunday's clash which gives Scotland confidence that their breakdown tactics will work again.
"We met South Africa a mere 151 days ago in Nelspruit and they've certainly played some quality footy since we gave them a bit of a scare that day," Johnson said.
"I was proud of a lot of what we did in Nelspruit, but in this business you have to perform for the entire game and we didn't do that in the match during mid-year.
"As I said last weekend and as you'll hear me say without fear or favour at every game, the contact area will be vital this weekend and we have to improve there against a very clinical South African side."
Scotland's defence coach Matt Taylor believes the Boks will be more dangerous at Murrayfield than they were in Nelspruit.
"From what I've seen in the (Rugby) Championship they can play two different styles of game," he said.
"They can certainly play an attacking style keeping the ball in hand, but they can also stick it up the jumper, and drive it and kick it as well, so I think they have a Plan A and Plan B depending on how they want to play it.
"I think they have improved overall as a team in attack and defence from when we played them; they're using the ball more and better than they have in the past."
